Correction Algorithm For Sound Scattering Coefficient Measurements
The 22nd International Congress on Acoustics, Buenos Aires, 2016 Scattering coefficient measurements according to ISO 17497-1 are very sensitive to temperature and humidity changes in the reverberant room. Even variations as small as 0.1 K can significantly influence effective reverberation times and lead to wrong results.

Integral identities for reflection, transmission, and scattering coefficients
The Journal of the Acoustical Society of America, 2018 Several integral identities related to acoustic scattering are presented. In each case the identity involves the integral over frequency of a physical quantity. For instance, the integrated transmission loss, a measure of the transmitted acoustic energy through an inhomogeneous layer, is shown to have a simple expression in terms of spatially averaged ...

Advanced Functional Materials, EarlyView.For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,
